Abstract

High-frequency radiations are used to study the decolorisation of the chelate of Chrome Azurol S with aluminiumIII. The chelate is more stable than the dye itself towards the activity of ultrasonic waves. A fall in the pH of the chelate solution is observed on exposing it to ultrasound for different periods of time, whereas there is a regular increase in the specific conductivity. Absorption curves from spectrophotometric data demonstrate the fading of the colour of the dye and of the chelate with time of exposure. Possible modes of destruction of the chelate and dye molecules from the cavitation energy produced during the passage of ultrasonic waves are suggested.
